Specification of Letters Patent.

Patented Oct. i3, 1914;

To all 1 0/0m 'it may concern.'

lle it known that we, RICHARD K. Ln linoivn and lflliLLiAM l?. (luci-inn, citizens of the `United States' of America. and residents of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful linprovements in Lathes, of which the following is a specification.

This invention is an improvement in lathes and has for an object to produce a lathe having improved means for preventing the feed drive and the traverse drive of the tailstoclt or tool-carrying member from being,- simultaneously thrown into operation.

A further object is to produce a lathe having` new and improved means for preventing the traverse drive mechanism from operating the hand or pilot wheel of the lathe and thereby eliminatingl the danger ordinarily encountered in lathes, due to the whirling of the pilot wheel when the traverse drive mechanism is thrown into operation.

A, further object is an improved lathe which is more effective in operation and is easier to manipulate than other lathes kno-wn to us.

These and other objects we attain by means of a lathe embodying' the features herein described and illustrated.

ln the drawings accompanyingv and forming a part of this application, Figure l is a fragmental sectional plan view along` the broken line l-l cf Fig', 3; Fig. 2 is a fragmental sectional View along the line Q of -l `ig. El; Fig. i is a fragmental sectifnal view along the broken line of Fig. l g Fig. Il is afragmental sectional view alrfng the broken line 4 1 of Fig. l and lD is a fraginental sectional view along the line 5---53 of Fig'. l.

rlhe lathe herein illustrated as an embodiment of our invention includes the usual frame 5, the usual head-stock and chuck, which are not herein shown, and a. toolcarrying clement or tirol-slideti, which is capable of moving` along ways or shears 8 provided on the frame 5,

The tool-slide (l is reciprocated along its ways by means of two independent power shafts 9 ,and 10; thc latter of which i's eluded Ein a .power transmission mechanism for the tool-slide which isordinarily termed the feed drive Q while the other forms' a part of a power transmission mechanism which sometimes termed the traverse drive and which is employed in the preliminary operation of moving the tool up to the work on the head-stock, and also in the operation of withdrawing the tool from the work. f

ln addition to the feed and traverse drive mechanism-the latheis provided with the lusual pilot wheel i4 which is mounted on a shaft forming a part of the feeddrive and is employed in shifting the tool-slide in the final operation of adjusting the tool t0 the work on the head-stock. The feed drive and the traverse drive mechanisms each coperate with a rack 11, in actuating the toolmeshes with the rack, and an actuating gear 13, which is shown as integrally formed with the pinion l2. Means are provided for preventing the traverse drive mechanism from being thrown intooperation while the feed drive mechanism isoperating, and Vice 70 slide' and cach includes a pinion 12, which" versa, for preventing the feed drive from' being thrown in while the traverse mecha nism is in operation, so that the pilot Wheel 141-, will not be spun around at a dangerous speed while the traverse mechanism is in operation. The means illustrated for accomplishing" this, includes a single handle 15, which is capable of simultaneously actuating two separate clutch devices so that one transmission mechanism isrendered operative and the other is rendered inoperative. ln the apparatus illustrated, the handle l5 has the additional function of shifting the clutch device, forming a part of the traverse mechanism so that the tool-slide y may be reversed in its movement along the ways and may he rapidly moved 'up to or withdrawn from the work on the head-stock. I The shaft 9 of the traverse drive l eX- tends along' the frame parallel to the ways 8and is provided with any suitable actuating` means, such as are .ordinarily employed and are usually located at the headend of the lathe. A bevel pinion 16 is splined onto the shaft 9 so that it is capable of being rotated by theshaft, and at the same time moving logitiidinally of the shaft. An elongated hub, or, laterally pro jecting .sleeve 1'? is shown as integrally formed with the pinion 16 for the purpose 4of increasing the vbearing surface between it andthe shaft, and also for providing adequate bearing surface between lthe pinion and an extension 18, which is provided on the tool-slide and in Which the sleeve 17 is journaled. A bevel gear 2O meshes With the' pinion 16and is rigidly mounted on one end of a shaft 21, which is journaled in a suitable bearing provided in the body of the g with the Abevel gear tool-slide, and on the a second bevel gear 22 is rigidly mounted. The gear 22 is continuously in mesh with two oppositely disposed bevel gears 23 and 24, which are loosely mounted on a shaft 25 and are located diametrically opposite to each other, with respect to the gear 22 s0 that they are driven in opposite directions by it.-

A clutch member 26 is splined onto the shaft 25 and is adapted to be moved along the shaft 25 for the purpose of operatively connecting it to one or the other of the gears 23 and 24. Each lateral'face of the clutch member 26 is provided with a series of teeth 26 which are adapted to cooperate with similar teeth formed on one lateral face of each of the gears 23 and 24 and to other end of which f' thereby operatively lock one of the gears to the shaft 25 When the clutch member 26 is moved into engagement With it. The shaft 25 is suitably journaled Within the body of the tool-slide and is provided at its inner end with-a rigidly meshes With the gear 13 and therefore ac# tuat'es the pinion 12 which meshes with the rack. With this arrangement the tool-slide when the clutch member 26 is in engagement 23 and it is moved in the other direction when the clutch member `is in engagement with the gear 24, since the rotation of the shaft 25 and consequently of the gears27, 13 and 12-is reversed when the clutch member is disconnected from one of the gears 23 and 24 and is moved into engagement With the other. The rotation of the pinion 12 causes the pinion to roll along the rack 11 and this causes the tool-slide to move along its ways With the pinion.

The feed drive mechanism includes the shaft 10 which extends parallel to the Ways 8 and consequently to the shaft t). A worm 28 is shown splined to the shaft 10 and meshing with a Worm Wheel 29 which is rigidly mounted on a shaft 30, journaled in the body of the tool-slide. The Worm 2S is located between tivo opposed faces provided on the tool-slide body so that it is moved along the shaft 10 ivith the tool-slide and is prevented from moving laterally with relation to the wheel 29. A gear 3l is loosely mounted on the shaft30 and is adapted to be operatively connected to it by means of a clutch device, which as herein shown, consists ^f.teeth 29 formed on the lateral face of the Wheel 29 and cooperating teeth 31 in.

`1neans` of a shoulder 39,

mounted gear 27, whichv 1s moved in one direction along its ivays the teeth of a cooperating gear 32, when the gear 31 is shifted longitudinally for the purpose of moving into and out of clutching engagement with the Worm Wheel 29. The gear 32 is rigidly mounted on a .shaft 3 3, which is provided with a gear 34 herein shown formed integrally with th shaft 33, its teeth being cut in the sur ace of the shaft. A gear 35 meshes With the gear 34 and is loosely mounted on a sleeve 36, Which surrounds a shaft 37, and is capable of mov-- ing longitudinally of the shaft. A gear 33 is mounted on the sleeve ble of rotating relatively prevented from` moving alongA the sleeve by formed on the sleeve and located on one side yof it, and a collar 40 located on the other side of it and secured to the sleeve by any suitable means, such as a set screw. One lateral face of the gear 38 is provided with teeth 41, which cooperate ivith teeth 42, formed on the lateral face of an elongated hub, with Which the gear 35 is provided. The sleeve 36 is capable of being moved along'the shaft 37 to such an vextent that the gear 38 shifts suffieiently to move its teeth 41 into and out of engagement with the teeth 42 of the gear The gear 35 is prevented from moving longitudinally With the sleeve 36 by means of a collar 43, mounted on the shaft 33, and an ,abutting surface 44, provided' on a convenient portion of the tool-slide body. The collar 43 is located adjacent to the gear 34 so that it forms a shroud for its teeth and con sequently engages the ends of the teeth of the gear 35 and prevents the gear 35 from moving in one direction, While the surface 44- prevents it from moving in the other direction, relativelytp the gear 34. The gear 3S meshes With the gear 27, 'on the shaft 25 and is provided with elongated teeth for the purpose of continuing it in mesh with the gear 27, While it is in the different longitudinal positions.

When the gear 31 is shifted so as -to lock it to the Worm Wheel 29 and the gear 38 is shifted so as to lock it to the gear 35 the feed drive transmission mechanismis rende'red operative and moves the tool-slide along its Ways in the following manner. The shaft 10 is driven by suitable means such as is ordinarily employed in lathes and drives the Worm 2S, which in turndrives the worm Wheel 29. The Worm Wheel drives the shaft 33 through the agency of the gears 31 and 32, and the gear 34, cut into the shaft 33, drives the gear 27 through the agency ofthe interloeled gears 35 and 38. The gear 27 drives the gear 13 and the pinion 12 and thereby causes the pinion to roll along so that. `it is capa- *i thereto, but it is the sleeve 36, is moved ,to such a. position lill) CII that the gear 38 is locked to the gear The sleeve is actuated by the handle 15 which is rigidly mounted on the shaft 37 and isprovided with a radially extending Flange 4G cn which teeth 46', having .inclinedlateral faces, are mounted. The teeth are located on a lateral face of the flange 46 and are adapted to engage grooves 47 formed in the lateral face of a similar flange 47, which is located on the end of the sleeve 3G. The

sleeve is prevented from turning with the shaft37 by any suitable means, such for eX- ample, as a stationary lcey 4S which engages a. groove formed in the bearing face surrounding the sleeve and which projects into aslot formed in the sleeve. l.Vith this arrangement the sleeve will be shifted longitudinally along the shaft 3,7 when the handle l5,- and consequently the shaft is turned so I; as to cause the inclined faces of the teeth 46 to ride up the inclined faces of the grooves 47 and 1n this manner force the flange 4T away. from the flange 46. This longitudinal motion of thesleeve 36 is resisted by a coiled spring 51, which surrounds the shaft 37 and is located between the inner lend of the sleeveand a collar 52 rigidly mounted on the shaft. .The teeth l46 are so constructed that they will shift the sleeve 36 longitudinally7 a sullicient amount to'disengage the teeth 4l, of the gear 38, from the teeth 42, of the gear and thereby permit the gear to rotate loosely on' thesleeve without transmitting power, when the handle is turned in either direction .from theV normal position.. The spring 5l also operates to shift the sleeve lback to its normal position so that the teeth 4l and 42 are interloelred, when the handle l5 is 'turned to its normal position in which the teeth 4G enter the grooves 47. ,The handle l5 is also capable of actuating' the clutch member 2G for the purpose of controlling the operation of the traverse drive mechanism. through the agency of la worm'f which is mounted on, or formed integrally with, the shaft 3T and meshes with a worm-rack or yoke 54. The yoke Vis capable of moving longitudinally in response to the rotation of the worm 53 and is provided with a finger 55 which engages'the clutch member 2G.

The worm and the yoke are so arranged that the yoke and. consetpiently the clutch member 9G occupy an intermediate positionwhen the handle 1.5 is in the' normal position, or that position in which th. teeth 46 enter the grooves 47. lilith this arrange.

IThis is accomplished ment the clutch member QG renders the traverse drive mechanism inoperative when the feed drive mechanism is operative and the yoke shifts the clutch member 2G into engagement with one of the gears or 24, when the handle l5 is turned in one direction or the other from its normal posi tion7 and after the feed drive mechanism has been rendered inoperative, by 'the disengagement of the gears 35 and 38. This causes the traverse drive mechanism to move the tool-slide toward the head-stock, in case the clutch member is in clutching engagement with the gear 2O, and away from the headstoclr if the clutch member is in engagement withvthc gear lnc pitch of the worm 53 and the altitude of the teeth 4G are so proportioned that thedisengagement of the gears and 3S and the engagement of the 'clutch member 2G with one of the Q3 and-2 4 are luiproximately simultaneous operations and consequently it is impossible to render the traverse drive mechanism operative while vthe feed drive mechanism is in operation. The first moveu ment of the handle 15, while it is being turned back to its normal position, renders the traverse drive mechanism inoperative by shifting the clutch member 2G to an inoperativeposition and the handle then renders the feed drive mechanism operative by coupling the gears 35 and 3S together, as has been described.' These two operations are also substantially simultaneous and therefore prevent the feed drive 7 mechanism from being thrown into'operation while the traverse drive l mechanism is in operation. Wlhile the traverse drive i mechanism is in operation the gear 38 rotates loosely on" the sleeve 36 and is therefore incapable of imparting the rotation of the gear 27 to the shaft 33 on which the pilot wheel 14. ismounted. Under these conditions there is no danger of the pilot wheel being turned at a. high velocity during the operation of the traverse mechanism.

One of the features of our invention is a new and improved means for automatically stopping the tool-'slide as it moves toward the rear `end of 'the ways while being actuated by thel traverse drive7 mechanism. The means herein illustrated consists. of a vertically extending rack tiyrhieh engages a gear 57 mounted. on, or integrally formed with the shaft 37, and normally projecting downwardly below the bottom. of the body portion of the tool-slide `so that its lower end may be 'engaged by a lug orstop 58,.

located on the frame 5` of the lathe. The projecting end of the rack is beveled and the stop 58 is inclined so that the rack will be moved lnpv'fardly when it contacts with .the stop. rlhis upward motion of the rack will `turn the shaft 37 and consequently shift theyoke 54. The stop isjso k.'lesigned that it' imparts suliicient motion to the rack to shift the yoke. so as to move the clutch member 26 out of engagement with the teeth on the gear 523. The stop is also of such length that the momentum of the tool-slide can not carry the pin past it after the traverse mechanism has been rendered inoperative. If desired, the :stop may bc of such height that it will not only render the traverse mechanisin inoperative but will also render the feed drive mechanism operative by moving the gear 38 into engagement With the gear and thereby reversing the motion of the tool-slide. It will also beunderstood that an additional stop 'may be'provided for checking the forward motion of the toolslide and that the stop may be adjustably mounted on the frame so that it maybe vemployed in stopping the 4tool-slide at various positions along the Ways.

le have also provided improved means ing enga gement with the wheel 29. The means illustrated consists of a bar or shaft 59 which is provided'at one end with the handle 59 and at the'othcr with a worm 60 which engages a volte-61 capable of reciprocat-ing as the handle is turned. A finger G2 is provided on the yoke and engages an annular groove formed in the gear 31. With this arrangement the gear 31 may be moved into locking engagement with the Wheel 29 by turning the handle in one direction and it may be Withdrawn from engagement with the Wheel by turning the handle in the other direction; This provides means for controlling the operation of the feed drive mechanism which is entirely independent of the handle l5. VVe-have provided means for holding the handle 59, and consequently the yoke 61, in either of their 'extreme positions. The means ilhistrate'd comprises a cani 623, mounted on the shaft 59, and a cooperating plunger 64C, which is continually held in contact with the peripheral face of the cam.

inclined grooves 65 are provided in the peripheral face of the cam for receiving the end oLl1v the plunger and these lgrooves are so located that cue or the other will cooperate 'with the plunger in holding the shaft.

against motion when the handle is turned to one or` the other of its extreme positions.

The handle 59 and the clutch mechanism operated by it arecapable of renderingr the feed drive mechanism inoperative. when it is desired to manually shift the tool-slide by means of the pilotv Wheel. The handle thereforel cooperates 4with the other mechanisrns employed in producing three separate means for shifting the tool-slide; that is, lthe hand operated means, the shaft 10 or the feed drive and the shaft 9 or the 9 traverse drive. f'hile the handle 59 can Abe employed in starting and stopping the feed drive, it cannot render the feed for shifting the gear 31 into and out of lockdrive effective as a driving agent for the tool-slide unless the handle 15 is in the normal position and the traverse drive 7 mechanism is inoperative.

A. feature of our invention is the arrangement of the power transmission mechanism so that the teeth 31 may remain in locking engagementwith the teeth 29 Without in any Way interfering withv the operation of the traverse drive -meeha sin. In other words the handle 59 may e turned to the normal operative position, r,so/as to lock the gear 31 to the gear 22h/While the' traverse drive mechanismhisabeing'eniployed to shift the tool-slide forward'and backward along the Ways. This arrangement simplifiesthe operation of the lathe, since it can be controlled almost entirely by the single operating lever l5.

We use the terni tool-slide throughout the specification and in the claims With no idea of limiting our invention to the specific forni of apparatus illustrated and We `lvish it to be understood that by' the term tool-slide We include all forms of reciprocal tool-carrying elements for lathes or similar machines.

In compliance with the United States patent statutes .ive have illustrated the preferred embodiment ofk our invention and described its functions and principles of operation, but We desire it to be understood that various changes, substitutions and modifications may be made Without departing from the spirit and scope of our invention as set forth in the appended claims.
